Por esta raz\u00f3n, alcanza la m\u00e1xima dureza dentro de la serie 420 tras el tratamiento t\u00e9rmico de templado y revenido.<\/p>\n<p>Asimismo, el <strong>AISI 420C<\/strong> permite desarrollar una microestructura sumamente dura y resistente a la abrasi\u00f3n. En consecuencia, resulta ideal para herramientas que requieren una retenci\u00f3n de filo superior. Por otro lado, ofrece una buena protecci\u00f3n contra la corrosi\u00f3n en aire y agua dulce.
